The Central Box 220 is a switchboard designed for the complete management of servos in a model with an emphasis
on safety. The Central Box 220 has a unique design that provides overload protection for up to 11 Standard
(up to 415 oz/in, 30 kg/cm) and 4 Ultra Torque (up to 830 oz/in, 60 kg/cm) servos. The Central Box 220
features true Battery Redundancy, Ditex Servo Telemetry, Jeti EX Telemetry, and up to three receiver inputs
(2x 2.4GHz and 1x 900MHz) with serial (PPM, EX Bus) output for complete Power & RF Signal Redundancy.
With Jeti Duplex 2.4GHz DC/DS transmitters, the full potential of the Central Box can be used, such as easy
way to wirelessly configure the Servo Outputs, Ditex Servo & EX Telemetry, Fail-Safe Setting or Function Assignment.

The power batteries are connected to the Central Box using MPX connectors. The Central Box allows two
batteries to be connected. During use, the power is actually supplied from the battery with the higher
voltage. If the voltage is the same, the power can be used from both batteries at the same time. When the
voltage of the batteries is different, the power is not shared and each pack is isolated from the other.
This allows you to use batteries of different capacity, number of cells and chemistry type. If the power
for the Central Box is provided only from one battery, it can be connected via battery (BATT 1) Input.
Magnetic Switch (Included)
The magnetic switch is used to turn the Central Box ON/OFF and is connected to a separate slot labeled
"SW". To turn on the Central Box using the magnetic switch it is necessary to hold the supplied
magnet (key) to the target so that the key and the target on the magnetic switch are properly oriented.
Wireless Switch R3/RSW (Optional)
State-of-the-art device that sets Jeti as a leading designer and manufacturer of radio control systems.
Wireless power switch is fully integrated into the 2.4GHz radio system. For first time your receiver can
be turned ON/OFF with simple flipping of the switch wirelessly from the Jeti DC/DS transmitters.

Switches ON/OFF of the Fail-Safe function. If the Fail-Safe function is deactivated, there is no signal
generated in any Central Box outputs at the signal loss. If you activate the Fail Safe function, you can
also select how the Central Box responds at signal loss for each of the individual outputs.
Servo No. - Assigning outputs of the transmitter to the Central Box outputs.
Group - Assigning specific output to the group of output impulses that will be generated from the receiver
in the same time.
Ditex Servo Telemetry
The Ditex telemetry servos offer groundbreaking design features combined with incredible reliability.
Advanced radio control telemetry systems such as Jeti Duplex are capable of providing real-time information
including complete telemetry data (Torque, Min/Max Current, Voltage, Angle, Telemetry Alarms) and full

After receiving numerous questions regarding getting extra channels while using Jeti Central Box 210/220 we have come up with elegant configuration that uses power from CB210/220 servo port 9/10 for Central Box 100. This way you can have up to 20 high power servos connected to the system and still have full battery telemetry & redundancy.
If you connect Telemetry to the CB100 and use CB100 only for noncritical functions (Gyro, Lights, Airbrakes…) you can get away with a single power lead and go up to 22 servos.
